What is TTS
TTS (Thrombosis with Thrombocytopenia Syndrome) causes blood clots and a low blood platelet count in humans. TTS can be caused by bone marrow disorders or an immune system problem. It can be a side effect of taking certain medications. TTS can affect both children and adults.
The admission was made by AstraZeneca at the High Court in February, in a class action lawsuit over claims its vaccine caused death and serious injury in 51 cases.
What AstraZeneca said
"It is admitted that the AZ vaccine can, in very rare cases, cause TTS. The causal mechanism is not known...Further, TTS can also occur in the absence of the AZ vaccine (or any vaccine). Causation in any individual case will be a matter for expert evidence," AstraZeneca said.

What complainants allege
AstraZeneca is being sued for over ?100 million (a little over Rs 1,000 crore) by those who suffered health complications, allegedly after receiving the COVID-19 vaccine shots.
According to one of the complainants, Jamie Scott, he had received the vaccine in April 2021 which caused him a permanent brain injury after a blood clot. This has prevented him from working and the hospital even told his wife thrice that he's going to die.
In the past AstraZeneca had denied any links between its vaccines and TTS.
